IMPROVEMENT IN WARPlNG-MACHINES.

Specification forming part of Letters Patent No. 205,307, dated June 25,187 8 application filed February 18, 1878.

To all whom it may concern:

Be it known that I, LoRmvzo L. SHAW, of Yarmouth, of the county ofCumberland and State of Maine, have invented a new and usefulImprovement in Machinery for Beaming Yarn or Winding Yarns upon a Beamor Roller; and do hereby declare the same to be described in thefollowing specification and represented in the accompanying drawings, ofWhich- Figure l is a top view, Fig. 2 an end elevation, Fig. 3 atransverse" section, and Fig. 4 a longitudinal section, of a machineembodying my invention, the object of which is to lay or wind the yarnsin strands or separate series upon the beam, and to accomplish suchevenly as the load of the beam may increase in diameter.

In the common warpers or yarn beaming machines the threads from thespools are led in one series from the reed to the beam; but in mymachine, as hereinafter described, they are separated, and pass inseveral series from the reed through a set of traversing guides, andthence to the beam, whereby while it may be in revolution they are woundin strands upon it, each of which is laid in helices about the bcam,-andwith the coils of each helix close together. The object of thus layingthe yarns upon the beam is to enable them to be conveniently unwoundtherefrom, for being spun or converted into twisted strands. e

In the drawings, A denotes the frame of the machine; B, a creel orstand, provided with the series of spools a a a. O is the reed; D, theyarn-beam, and E its supporting and operative cylinder or roller. Theload b of the beam rests directly upon the circumference of the rollerE, which, when the machine is in operation, is revolved ata uniformspeed, and consequently causes the load-surface resting on it to revolveat a like speed, however the load may increase in diameter.

Between the reed and the yarn-beam D is a traversing bar, F, providedwith a series of staples, eyes, or reducing'guides, c c 0, arranged atequal distances apart, each of them being adapted to receive through itfour, or any other suitable number, of the yarns dfrom the reed, suchyarns being first led from the spools to and under andag'ainsta'guide-rod, f, and thence to and through the reed. r

The traversing, bar is supported in Ys or standards 9 g, to which it isto be so applied as to enable it to be moved lengthwise or traversedtherein. For retracting it or movin g it backward, it has a spring, h,fixed to it and to one of the standards g,- but for moving it in theopposite direction, there is applied to it and to the shaft of theyarn-beam mechanism which may be thus described: Fixed on the shafti ofthe yarnbeam D is a' grooved wheel, it, about which and'a double-groovedwheel, m, an endless band, I, is led. This wheel m is pivoted to an armn, that is pivoted on a shaft, 0, arranged as represented. Anotherendless band, 1), engages the wheel m with a grooved wheel, q, fixed onthe shaft 0. There is a spring, 1', fastened to the frame, and bearingdownward the arm a, in order to keep the belt I tight on its pulleys orwheels and allow the yarn-beam to rise as its load may increase in size.

A worm or endless screw, s, fixed on the shaft 0, engages with aworm-gear, t, fastened on a cross-shaft, 'u, arranged as shown, andprovided with a heart-cam, '0, upon whose pe riphery the lower arm of anangular lever, w, rests. The upper arm of the saidlever bears against astud, a0, extending from the traverse- From the above it will be seenthat, while the yarn-beam may be in revolution, a slow reciprocatingrectilinear motion will be im parted to the said traversing bar, wherebythe strands will be caused to be laid or wound evenly' and properly onthe beam. As the load on the beam may increase in diameter the rotarymotion of the beam will become less or slower, whereby the traversingmove ments of the bar F will be correspondingly or so decreased invelocity as to cause the strands to be laid in even or close helices andlayers on the beam.

Thus, by driving the traversingbar mechan ism by the yarn-beam, thevelocity of traverse of the bar]? becomes decreased as the velocity ofthe beam may diminish in consequence of the increase of the size ordiameter of the load of yarn wound on the beam. By revolving the rolleron which the beam-load rests, the latter will be put in revolution, soas to cause the yarns to be drawn off the spools and Wound on the beamor load thereof.

What I claimas my invention or improvement in the yarn-beaming machineis as follows, that is to say:

1. In combination with the reed O, the yarnbeam D, and its supportingand operative roller or cylinder E, the traversing bar F, its series ofreducing-guides o, and the mechanism applied to the said bar and to theshaft of the yarn-beam, and consisting of the grooved wheels is m g,endless bands Z 1o, arm n, springs a" h, shafts 0 u, worm s, Worm-geart, heart-cam v, and lever 'w, arranged and applied as set forth, itbeing formoving the trayersing bars with a variable reciprocating motionin accordance with the Variable rotary motion of the beam as the load ofthe latter may increase in diameter.

2; The combination substantially as desscribed, applied to thetraversing bar and to the yarn-beam for moving the former by the latter,as specified, it consisting of the grooved Wheels 70 m g, endless bandsZ arm n, springs r h, shafts o u, worm s, worm-gear t, heart-cam v, andlever 10, arranged and applied as represented.
